Alexandre Diaz

PhD Student


Alexandre graduated in 2012 from The University of Reading with an MEng in Robotics and proceeded to work as a field engineer for Schlumberger, specialising in the design and installation of electric submersible pumps (ESP), undertaking an 8 month tour of the North Sea's Forties oil field. He then moved on to work for CRESS Systems as the lead electronic and control engineer, where he designed the condition monitoring systems for a prototype flywheel energy storage system. Joining the University of Cambridge and the EPSRC Centre for Doctoral Training in Ultra Precision in 2014, under the supervision of Professor Bill O'Neill, he is now undertaking a joint PhD project between the Institute for Manufacturing and the Diamond Light Source synchrotron facility.

Current research

Alexandre’s current research project investigates a new methodology to improve X-Ray crystallography and nano-particle measurement processes, by improving the current sample delivery and acquisitions system in one of Diamond’s synchrotron beamline detectors. This will be achieved by replacing the current robotic hardware by a commercial, off the shelf, optical tweezing system. The optical tweezers will trap and manipulate the particles of interest, by implementation of a 1064nm laser and optofluidic assembly. Using this technique, the project aims to increase the synchrotron beamline sample targeting accuracy, speed and measurement quality.
